the n_lstm_steps problem

[3015218116]

In the code, I found all the caption for the filtering operation, the frequency is less than a certain number, will not be counted, I found a place, I think this place is not very serious, at first we don't have any filter for the caption, take the longest as n_steps the length of the caption, we to take less than the length of the caption 0 extended length, but when we feed the data after filtering. That means even the longest caption means it means we need to fill it with zero. Any Suggestions?
